Abstract

La présente invention concerne des systèmes et des procédés de surveillance de la pression artérielle indirects, oscillométriques et numériques permettant un auto-étalonnage pour obtenir des valeurs absolues de pression artérielle à l'aide d'une analyse algorithmique de poises de pression artérielle afin d'établir un profil oscillométrique et de compenser des effets intervenant sur la pression artérielle numérique. Une analyse algorithmique appropriée dépend du positionnement correct et de la prise maintenue d'un manchon digital sur le doigt d'un utilisateur et d'un couplage hydraulique ultérieur du manchon aux artères à l'intérieur du doigt.
